Can you be more specific?

I'm not trying to be a jerk, but as far as I know Dinesh D'Souza is not a historian and probably doesn't claim to be one. He seems pretty firmly set in the "political" side of things. Googling his name with "historian" by it doesn't return any results calling him one, for example.

Is there a book in particular or a theory of his regarding history that you are wanting critically analyzed? We've got the 20-year rule, after all, and most of what Mr. D'Souza does/writes seems to be more focused on the present day than on the past.
